When a person is injured due to a product and wants to sue, the lawyer must investigate whether the product was defectively designed or manufactured. One must look at every step of the process to determine what went wrong, from the drawing board to the finished product. Design defects are exactly what they sound like, a defect in the design that is not picked up in testing.
Manufacturing defects occur when specifications are not followed during the manufacturing process. Some or all of the product may be defective depending on the nature of the defect and how many were defectively manufactured.
Sometimes defectively designed or manufactured products are recalled because they present a significant danger to the public. If you are injured by a product, you should consult with an experienced product liability attorney like Cohn Lifland.
